Abstract: Devices, methods, and systems for determining pushback direction are described herein. One method includes receiving a video image of an aircraft during a pushback of the aircraft, determining a motion flow map associated with the video image during the pushback, determining a motion orientation histogram associated with the video image during the pushback, and determining a direction of the pushback based on the motion flow map and the motion orientation histogram.
